Left Shoulder Pain/Band Pain???

I had my lapband surgery on 12/14/05 in Oklahoma. I have lost over 60 pounds. I have two issues that I would LOVE to hear from other lap band patients about if you have had these same issues. 1) I have 3.5 cc in my band and I seem to be stuck and not loosing any weight. I know this band holds 4.0 but as much as I'm complaining about NOT loosing, they don't seem to want to increase the amount to 3.75 or 3.8. I know from other notes I've seen on the web that other patients have this amount. I borrowed $12000 to pay for this and at $320 a month to Capital One I need to be loosing some weight !!! My most major complaint is this pain I have in my upper diaphram (spelling?) sorry. and my left shoulder. The first time I had this was around February and I went to the ER thinking I was having a heart attack. I was in tears it hurt so much. After thousands of dollars worth of tests I was told "It must be your lap band." Well the lap band surgeon says this band is OK and that is not the problem. I know the shoulder pain is radiated pain from the other area. PLEASE let me know if you have this problem. I have this pain days at a time and it will go away as strangely as it appears. Thanks!
